RHODE ISLAND, ASSIGNORS TO HEMPHILL COMPANY, OF CENTRAL FALLS, RHODEISLAND, A CORPORATION OF MASSACHUSETTS KNITTING MACHINE OPERATINGMECHANISM- Application filed January 8,

This invention relates to knitting machine operating 7 mechanism.

In order that the principle of the invention may be readily understood,we have disclosed one embodiment of means for practising the same in theaccompanying drawings, where- Fig. 1 is a rear elevation of a portion ofthe operating mechanism of a circular knitting machine; a

Fig. 2 is a side elevation viewed from the right of Fig.1 with one ofthe side frames of the machine removed Fig. 8 is a vertical section onthe line 33 of Fig. 2'; and a Fig. 4 is a plan view of the mechanismshown in the other figures.

While this invention is not restricted to circular knitting machines ofthe Banner type, it is particularly applicable thereto in that itinvolves novel means for supporting and operating the so-called 104 gearof the Banner machine of the general type shown in the patent to JoshuaD. Hemphill, No. 933,443, and many subsequent patents.

Heretofore the 104 gear has been mounted upon a stud extending throughone of the frames only of the machine, and it has been impossible withthe prior construction, to support the same upon a shaft with twobearings because the 104 gear has heretofore been provided upon one facewith a pin to which a connecting rod is suitably connected. The propermovements of such connecting rod would have been impossible if a shafthad been provided for the 104 gear. According 'to the present inventionthe said pin and connecting rod are replaced by an eccentric and itsconnecting rod, as hereinafter disclosed, and the 104 gear is mountedupon a horizontal shaft supported in two uprights of the framing.Attention is called to the patent to Lawson & Lawson, No. 1,702,608,dated February 19, 1929, wherein the gear 7 is identified as the 104gear. This gear is a characteristic element of the Banner knittingmachine, and the present invention is directed to improved means forsupporting and operating the same.

Referring more particularly to the drawsource.

ings, we'have, in Figs. 1, 3 and 4, represented the two uprights oftheframing at 1, 2, and we have therein provided openings 3 and 4 inconnection with which we provide suitable bearings indicated generallyat 5and6; Said bearings themselves may be of any suitable character ortype, and it is unnecessary to describe the same in detail.

; The bearing shown at 5 is or may be the I 7 gear is receivedisindicated' at 7, andthe-104 gear itself is indicated at 8. The saidshaft is :novel in thisorganization, and is represented as broken awayat its two ends, which ends, oreither of them, may receive cams'or Utherefor. A suitable cover 12 is also provided.

In Figs. 1,=3land;4, the usual clutch member 13 is provided adapted tomesh as usual with the clutch members 14 and 15 which need not be fullydescribed further than to state that the clutch member 15 has integralor formed therewith the pinion 16 which is reciprocated by the quadrant17 Thesaid stud 21 having thereon a collar '22, as indicated clearly inFig. 3. The clutch member 14 has fast therewith the pinion 23 by whichthe 104 gear is itself driven from the usual By the foregoingconstruction the 104 gear is more satisfactorily supported and withoutstrain than in the former construcstood that although specific-terms areemployed, they are used in a generic and descriptive sense and not forpurposes of limitation, the scope of the invention being set forth in 5the following claims.

We'claim: I 1. In a circular knitting machine of the socalled Bannertype, the 104 gear, a shaft for supporting thesame, spaced uprightmembers of the framing at opposite sides of said 104 gear, bearings forsaid shaft mounted in the said members of the framing of the ma- 1chine, an eccentric fast with said 104 gear vbetween said framingmembers, a connecting rod for said eccentric, the quadrant and pivot- Ial operatingvconnections between said connectingrod and said quadrant.

0 2.111 a circular knitting machine of the socalled Banner type, the 104gear, a shaft for supporting the same, spaced upright mem bers of theframing at opposite sides of said 104gear, two bearings for said shaftsupported upon the said members of the framing of' the machine, aneccentric, between said framing members upon said 104 gear andsurroundingsaidl shaft, a connecting rod extending from said eccentric,the quadrant for reciprocating the needle cylinder or reciprocableelement, and pivotal operating connece tions between said connecting rodand said quadrant. I 3. A circular knitting machine'of the socalledBanner type'having a quadrant, ashaft 1 e V whereon the same is mounted,a connecting rod pivotally connected to said quadrant, the

104 gear, an eccentric fast with said 104 7 gear and adaptedto operatesaid connecting rod, a shaft supporting said 104 gear, two bearings forsaid shaft at opposite sides re- 40 spectively of said 104 gear, and twospaced upright members of the framing to which said bearings arerespectively secured.

In testimony whereof, we have signed our names to this specification.
